Can I use a wildcard SSL certificate to resolve 'Bad Cert Domain' errors?

Yes, a wildcard SSL certificate (e.g., `*.example.com`) can often resolve the issue. A wildcard certificate secures all first-level subdomains of a domain. However, ensure the wildcard certificate is properly installed and covers all the subdomains you need to secure, and that Cloudflare is configured to use the certificate correctly. Incorrect setup can still lead to errors.
